Stability and dynamics of the flow past of a bullet-shaped blunt body moving in a pipe
P. Bonnefis, D. Fabre, C. Airiau
The flow past a bullet-shaped blunt body moving in a pipe is investigated through global linear stability analysis (LSA) and direct numerical simulation (DNS). A cartography of the…
